Real Housewives of Beverly Hills star Lisa Vanderpump has sold her huge Beverly Park Mega Mansion for a whopping $19-million and exclusively reveals to that "it's just too big for Ken and me." "We had such a great offer on the house, one we couldn't refuse," Lisa says. "It's 17,000 square feet and my daughter, Pandora and son, Max, already moved out of the nest. So it's just Ken and me and it's really too big for two people." Lisa's not going too far though; she's still remaining in the 90210 hood.
